Encoder Test Input - solved #285

Closed u2fletch closed 9 months ago

u2fletch commented 9 months ago

ELS was working great, but had an issue where the 5v power supply I had in electronics enclosure died horribly. I replaced with a 5v DIN package power supply, but now my ELS display is not displaying any rotation. I have a spare encoder, but no change. I also have a spare TI board, so flashed that, and again, no luck with encoder. I've ordered a new ELS board from Ebay, but while I am waiting I wondered if there is a good place to inject a signal to troubleshoot the ELS board? I have a signal generator and digital scope, so just looking for good places to probe.

Thanks for your input.

ELS is working again. Replaced the TI board as stated above, but realized later that evening the encoder input jumpers were not repositioned. Switched those out and now the encoder is reading once again.
